Ingredients Equipment Method Notes

Ingredients
  

For the Beef
  • 1 lb flank steak thinly sliced against the grain
  • 1 tbsp soy sauce
  • 1 tsp cornstarch
  • 1 tsp sesame oil
For the Sauce
  • 1/4 cup beef broth
  • 2 tbsp soy sauce
  • 1 tbsp oyster sauce
  • 1 tsp sugar
  • 1 tsp cornstarch
For the Stir-fry
  • 2 tbsp vegetable oil divided
  • 1 large onion sliced
  • 2 cloves garlic minced
  • 1 tsp fresh ginger minced

Equipment

  • Wok or large skillet
  • Knife
  • Cutting board
  • Small bowl

Method
 

  1. In a small bowl, combine the sliced flank steak with 1 tablespoon soy sauce, 1 teaspoon cornstarch, and 1 teaspoon sesame oil. Toss to coat and set aside.
  2. In another small bowl, whisk together the beef broth, 2 tablespoons soy sauce, oyster sauce, sugar, and 1 teaspoon cornstarch for the sauce. Set aside.
  3. Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat. Add the marinated beef and stir-fry until browned, about 2-3 minutes. Remove beef from the wok and set aside.
  4. Add the remaining 1 tablespoon of vegetable oil to the wok. Add the sliced onion, red bell pepper, and green bell pepper. Stir-fry until crisp-tender, about 3-4 minutes.
  5. Add the minced garlic and ginger to the wok and stir-fry for 30 seconds until fragrant.
  6. Return the beef to the wok. Give the sauce a quick stir and pour it over the beef and vegetables. Cook, stirring constantly, until the sauce thickens, about 1-2 minutes.
  7. Serve immediately over rice.

Notes

For a spicier dish, add a pinch of red pepper flakes with the garlic and ginger. You can also add other vegetables like broccoli florets or snow peas.
